Solution by Steps
step 1
We start by factoring the quadratic expression 2z217z+352z^2 - 17z + 35
step 2
We look for two numbers that multiply to 235=702 \cdot 35 = 70 and add up to 17-17. These numbers are 7-7 and 10-10
step 3
Rewrite the middle term using these numbers: 2z27z10z+352z^2 - 7z - 10z + 35
step 4
Factor by grouping: z(2z7)5(2z7)z(2z - 7) - 5(2z - 7)
step 5
Factor out the common term: (2z7)(z5)(2z - 7)(z - 5)
Answer
(2z7)(z5)(2z - 7)(z - 5)
Key Concept
Factoring Quadratics
Explanation
To factor a quadratic expression, we look for two numbers that multiply to the product of the leading coefficient and the constant term, and add up to the middle coefficient. We then use these numbers to split the middle term and factor by grouping.
